LOOM-SHUTTLE.-

SPECIFICATION forming part of Letters Patent No. 255,953, dated April 4, 1882.

Application filed June 27, 1881. (No model.)

To all whom it may concern Be it known that I, SUMNER A. DUDLEY, of Wilkinsonville, county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Loom- Shuttles; and I do hereby declare that the following, is a full, clear, and exact description of the same, reference being bad to the accompa'nying drawings,forming a part of this specification, and in which Figure 1 represents a top or plan view of an ordinary shuttle and bobbin with my improvements applied thereto. Fig. 2 represents, upon an enlarged scale, a vertical central section through a part of the shuttle shown in Fig. 1, taken on line a, a of said Fig. 1, looking in the direction indicated by arrow b, showing a portion of the shuttle-body and bobbin in section, and a side view of the shuttle-spindle, as will be hereinafter more fully described; and Figs. 3 and 4 represent, upon the same enlarged scale as Fig.2, a side and bottom view, respectively,of the shuttle-spindle, the latter looking in the direction indicated by arrow 0, Fig. 3.

The nature of my invention consists in the combination, with a shuttle-body, of a spindle provided with-a shoulder upon one side thereof, a spring secured to the rear end of said spindle and adapted to press upon the outer periphery of a bobbin, opposite the shoulder upon the spindle, a transverse pin secured to the shuttle-body between the spindle and its spring, and a knuckle provided with a spring and adapted to press into a curved recess in the rear of the shuttle-spindle,as will be hereinafter described, and fully pointed out in the claims.

To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it more in detail.

In the drawings, (1 represents an ordinary shuttle-body; e, one of my improved shuttlespindles, andfa bobbin applied to the same. The shuttlespindle c is hinged to the shuttlebody d by means of a pin, 4, passed through said shuttle-body and the base end 6 of the spindle 0. Upon the base end 0 of shuttlespindle e is secured, at h, a flat spring, h, by means of which the bobbin is held upon the spindle e, as will be hereinafter more fully explained. The shuttle-spindle is held in position when swung up or out, as represented by dotted lines in Fig. 2, and when sprung down into the slot of the shuttle-bod y, as represented by full lines in Figs. 1 and 2, by means-of spiral spring, k, and knuckle l, (over which said spring is arranged,) the latter being provided with a rounded head, I, that fits into the curved part m of the shuttle-iron. Said curved part or recess m is formed at the proper point above the pivotal bearing of the shuttle-spindle to firmly hold the same in the position shown by full lines, with its base end bearing against the surface it of the shuttle-body, and in its elevated position, as shown by dotted lines, after having been sprung up by hand, by bearing below its pivotal bearing with the upper side of the iron bearing against the surface 0 ot' the shuttle-body.

In springing the spindle 0 out, as represented by dotted lines in Fig. 2, the spring h is forced and held back away from said spindle by bearing upon a stationary pin, p, secured in the shuttle-body, thereby enabling the bobbin to be applied to or removed from the spindle in an easy and convenient manner. After a bobbin has been applied to the spindle with the shoulder 9 back of the shoulder q of the bobbin the spindle, with the bobbin upon it, is sprung down into the position represented by full lines in the drawings, thus allowing the spring h to bear upon the outer side of the head of the bobbin, which holds the latter firmly in position between shoulder 9 upon the inside of the barrel of the bobbin and spring h, which presses against the outer surface of the bobbinbarrel and opposite shoulder, 9, thereby obviating and remedying the serious objections to the old internal bobbin-holding devices, which have tended to split the bobbins, there being no outward resisting pressure device to prevent the strain coming upon the interior of the Those skilled in the art to which my invention belongs will readily see and understand that the invention simplifies the construction of shuttles, while at the same time the constant splitting of the bobbins incident to the old internal outwardly-pressing holding devices will result in a great saving of bobbins and yarn-two items of great importance to manufacturers.

It will be understood by those skilled in the art to which my invention belongs that the bobbin pressing and holding spring It may be diflerently applied and still perform the function of holding the bobbin in combination with the shoulder g on the base of the spindle e, and therefore I do not limit myself to the particular mode shown. 1

Havingdeseribed my improvements in 100111- shuttles, What I'claim therein as new and of my invention,and desire to secure by Letters Patent, is-

1. The combination, with shuttle-body d, of shuttle-spindle 0, provided with shoulder g on one side thereof, spring h, adapted to press upon the outer periphery of a bobbin, and stationary pin p, insertedin the shuttle-body between the shuttle-spiudle and its spring, substantially as and for the purposes set forth.

2. The combination ofa bobbin pressing and binding spring, h, constructed to bear against the outside of a bobbin, and the shuttle-spindle e, provided with the bobbin-holding shoulder g, and curved recess m, with spring 70 and knuckle l l, substantially as and for the purposes set forth.

3. The combination of a shuttle-spindle provided with a shoulder,g, and a bobbin-holding springadapted to press against the outside of a bobbin provided with an internal shoulder and hold the same in engagement with the shoulderg upon the spindle, with means for relieving the pressure of the spring, substantially as set forth.
